Explanation Given information: tanh ( u + v ) Formula used: sinh ( u + v ) = sinh u cosh v + cosh u sinh v cosh ( u + v ) = cosh u cosh v + sinh u sinh v Calculation: The addition identities for hyperbolic sine and cosine are. sinh ( u + v ) = sinh u cosh v + cosh u sinh v cosh ( u + v ) = cosh u cosh v + sinh u sinh v Dividing these will give us the following relation. tanh ( u + v ) = sinh u cosh v + cosh u sinh v cosh u cosh v + sinh u sinh v We can simplify this relation by dividing both the numerator and the denominator by cosh u cos v and simplifying

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
